Abstract

Production of ethanol by a process in which a strain of Bacillus stearothermophilus or other thermophilic, facultatively anaerrobic bacterium is selected for the characteristics of fermenting sugars both aerobically and anaerobically and of being active in anaerobic fermentation at 70 DEG C or above and (i) anaerobic fermentation is carried out with continuing removal of ethanol at 70 DEG C or above; (ii) the fermentative activity of the bacterium is maintained by withdrawing a proportion of the anaerobic fermentation medium on a continuing basis preferably with removal of ethanol and allowing the bacteria therein to multiply aerobically, using residual sugars or metabolites thereof present in the medium, before being returned to the anaerobic fermentation.
